  Elektrische Alarmvorrichtung. 



   Gegenstand der Erfindung betrifft eine elektrische Alarmvorrichtung, welche als Neuerung ein fortdauerndes Läuten aufweist, selbst wenn die auf den Faden einwirkende Störung sofort wieder beseitigt wird. 



   Auf   umstehender Zeichnung   ist der Erfindungsgegenstand in einer Figur schaubildlich dargestellt. 



   Elektrische Meldcapparate, besonders als Diebesalarmvorrichtungen sind bereits bekannt. jedoch unterscheidet sich vorliegende   Neuerung   gegenüber den bekannten Einrichtungen dadurch, dass, wenn der auf den Faden einwirkende Druck. Zug oder sonstige Störungen sofort wieder aufhören, ein Fortdauern des Läutens stattfindet. während bei den   bekannten Alarm-   vorrichtungen die Glocke aufhört zu tönen, sobald die auf den Faden einwirkende   Störung   beseitigt wurde. 



   Der vorliegende Apparat besteht aus   einem     Kasten bzw. aus einem entsprechend   aus-

 einer   leitenden Verbindung   der beiden Federn der   Stromkreis geschlossen und eine Glocke zum     Tonen gebracht wird.   



   Dies wird erreicht   durch das elektrischleitende Gpwtcht f. welches an   dem Faden/frei

  Electric alarm device.



   The subject matter of the invention relates to an electrical alarm device which, as an innovation, has a continuous ringing, even if the disturbance acting on the thread is immediately eliminated.



   The subject of the invention is shown diagrammatically in a figure in the drawing below.



   Electric alarm devices, particularly as thief alarm devices, are already known. However, this innovation differs from the known devices in that when the pressure acting on the thread. The train or other disturbances stop immediately, the ringing continues. while in the known alarm devices the bell stops sounding as soon as the disturbance affecting the thread has been eliminated.



   The present apparatus consists of a box or a suitably equipped
 EMI1.1
 A conductive connection between the two springs closes the circuit and makes a bell ring.



   This is achieved through the electrically conductive power supply. which on the thread / free

 EMI1.3
 Material are made. further contacts to complete the circuit are not required.
